A compact solid polymer electrolyte fuel cell having a simplified structure of a high mechanical strength and an improved gas-sealing property is disclosed. In the solid polymer electrolyte fuel cell of the present invention, gas-tight electrically insulating layers are provided on the flanks or the insides of the module of the above-mentioned laminated unit cells, thereby to give a gas-tightness between said electrode and separator.

1. A solid polymer electrolyte fuel cell comprising a plurality of stacked unit cells, each two unit cells having an electrically conductive separator disposed therebetween, said unit cell comprising:a pair of electrodes each of which comprises a catalytic reaction layer, said pair of electrodes having a solid polymer electrolyte film disposed therebetween, a means for supplying and distributing a fuel gas mixture containing hydrogen to one surface of said pair of electrodes, and a means for supplying and distributing an oxidant gas containing oxygen to another surface of said pair of electrodes, wherein a gas-tight electrically insulating layer is provided on the flank of the stacked unit cell and in between the stacked unit cells, thereby to give a gas-tightness between said electrodes and said separator, said insulating layers covering outside end portions of said separators, each of said gas-tight insulating layers formed on the flank and in between the stacked unit cells being a unitary layer.
